Detuner is a generic term for a jet engine test cell exhaust system muffler. Aircraft jet engine testing facilities typically require a means to vent and dampen the engine exhaust. The engine exhaust flow is "augmented" with a relatively large flow of cooling air induced by a Venturi effect into the exhaust silencing system, so the exhaust ...
This lower flow but slightly quieter design approach is commonly used in glasspack mufflers. Some modern muffler designs are similar in principle to the glasspack, but use more sophisticated sound-absorbing materials such as stainless steel mesh, and more advanced acoustic engineering, reducing noise while retaining the power-preserving ...
The dynamic insertion loss of a sound attenuator is the amount of attenuation, in decibels, provided by the silencer under flow conditions. While flow conditions in typical low velocity duct systems rarely exceed 2000–3000 ft/min, sound attenuators for steam vents must withstand airflow velocities in the 15,000-20,000 ft/min. range.

Silencer (silver) and exhaust pipe on a Ducati motorcycle A silencer cut open to show the insulation, chambers and piping inside the shell. A muffler (North American and Australian English) [1] or silencer (British English) is a device for reducing the noise emitted by the exhaust of an internal combustion engine—especially a noise-deadening device forming part of the exhaust system of an ...
A Eurofighter Typhoon in a hush house facility with an air-cooled exhaust detuner. A hush house is an enclosed, noise-suppressed facility used for testing aircraft systems, including propulsion, mechanics, electronics, pneumatics, and others. [1] Installed or uninstalled jet engines can be run under actual load conditions.
